Title: Hydraulic oil well pump drive system
Inventor: STANLEY LLOYD
IPC: F04B53/00
Filed: 1993-03-01
Abstract: A hydraulic oil well pump drive system (100) for driving an oil well sucker rod (not shown) includes. a master piston (158) positioned within a master cylinder (156) for axial displacement between first and second ends of the master cylinder (156).    The master piston (158) has a piston drive rock (164) which extends through one end of the master cylinder (156). The drive rod (164) is connected to a crankpin (147) of an eccentric crank (144). The eccentric crank (144) is driven at a constant rotational speed to reciprocate the master piston (158) within the master cylinder (156) at a sinusoidal rate. A center seal assembly (168) divides the master cylinder (156) into a working chamber (170) and a pressure chamber (172) in opposite ends of the master cylinder (156). Each respective chamber defines a fluid volume which varies with the displacement of the master piston (158). The master piston (158) displacement creates a bi-directional flow of working fluid from the working chamber (170). A wellhead hydraulic assembly (111) is operably connected to the oil well sucker rod and is in fluid communication with the roaster cylinder working chamber (170) to receive the working fluid flow. The wellhead hydraulic assembly (111) is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston (158) displacement. A gas accumulator (176) is in fluid communication with the master cylinder pressure chamber (172) to bias the master piston (158) toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly (111).

The unique filter cartridge (10) broadly includes a casing (50) that has at least one open end with an inner lip (55a) in the casing (50) proximal to the open end; and a porous collar (60) that has first and second peripheral edges, at least one of which is coupled to the casing (50) along the inner ledge. A method of sealingly coupling a hollow fiber bundle (30) having first and second ends (31a, 31b) to a casing (50) for encasing said bundle of hollow fibers is also disclosed. The method broadly includes coupling an outer peripheral edge of a porous collar (60) to a hollow fiber filter casing, wherein the casing (50) has at least one open end with an inner lip (55a) proximal to the open end and wherein the outer peripheral edge of the porous collar (60) is coupled along the inner lip (55a); retaining the bundle of hollow fibers within a chamber defined by the casing (50); fluid impermeably potting the open end of the hollow fiber bundle (30) with a fluid impermeable material; and joining the porous collar (60) to the fluid impermeable material by penetration of the material into the porous collar (60). The method provides a fluid impermeable seal between the casing (50) and the individual unpotted hollow fibers. The seal prevents the unfiltered fluid from coming into contact with filtrate and provides a strong bond that is impervious to dry heat and steam sterilization at temperatures ranging from 100 ·C to 150 ·C and pressures from 10 psi to 60 psi.
